SHEET METAL CORNER FOR MIRROR FRAMES Filed Sept. 13, 1961 INVENTOR. 5/0/1/5) 67/1/10 ATTORNEY United States Patent 3,139,161 SHEET METAL CORNER FOR DR FRAMES Sidney Simon, 8324 Graham Ave, Los Angeles, Calif. Filed Sept. 13, 1961, Ser. No. 137,858 4 Claims. (Cl. 189-36) This invention relates to picture and mirror frames and more especially to sheet metal corners particularly for mirror frames and the like.

Pictures and mirror frames at the present time are frequently made of metal such as stainless steel, chrome plated steel, aluminum or other metal. These frames may have an L shaped or U shaped cross section. The corners of these frames are usually formed by cutting out a 90 section of the front Wall or flange and bending the side wall so that the confronting edges of the front wall meet in a mitered corner. These confronting or adjacent mitered edges are frequently left raw, however, they may be joined by a brazing or wedging operation of any suitable nature. These edge portions, however joined or left unjoined, usually present an undesirable appearance, being jagged or rough. The present invention has been developed to overcome these objections and deficiencies in prior corner constructions for pictures and mirror frames.

An object of the invention is to provide novel improvements in a corner construction for picture and mirror frames.

Another object of the invention is to provide a corner construction for picture and mirror frames wherein there are no meeting or facing edges of the frame wall or flange elements.

An additional object of the invention is to provide novel improvements in a corner construction for mirrors and picture frames wherein one of the edge portions of the adjacent mitered corner overlies the other in a manner to conceal the edge of the other part.

An additional object of the invention is to provide a frame structure as in the previous object wherein the overlying edge portion of one of the frame parts is raised or embossed and overlies the other to present a pleasing and aesthetic effect.

Other objects and advantages will appear and be brought out more fully in the following specification, reference being had to the accompanying drawings.

In the drawings:

FIGURE 1 is a partial front view of a corner section of a mirror frame, in partially formed condition, of an embodiment of the invention.

FIGURE 2 is a view of the same in completed condition.

FIGURE 3 is perspective view of the corner construction seen in FIGURE 2.

Referring to the drawings in more detail, the corner construction of this invention comprises a strip of sheet metal of any suitable or desired character, such as stainless steel, chrome plated steel, aluminum, brass or other metal, the strip being L shaped in crosssection to provide a side wall 11 and a front or facing wall 12. Front wall 12 is suitably notched or cut out as at 13, this cutout being preferably so made as to form an edge portion 14, making a 45 angle with the side wall 11. The adjacent front wall formed by the cutout has a somewhat curved edge 15 and the portion adjacent thereto at 16 is die formed or raised or otherwise embossed.

The frame is completed by forming the corner by bending the side Wall 11 at right angles, and as a result of this bending, the embossed or raised portion 16 will 3,139,161 Patented June 30, 1964 overlie the mitered straight edge of 14 of the adjacent frame section. .Thus no raw edges of the usual mitered joint will be apparent, nor will any marks of welding, brazing or the like appear, and the resulting frame corners will have a pleasing and attractive and aesthetic appearance.

It should be apparent to those skilled in the art that when making a complete frame for a mirror or a picture from a single metal strip that three of the corners can be formed by notching as at 13 and that the two ends of the strip will need to be formed as a miter as at 14 and with the curved and raised edge portion 15 overlying the mitered edge 14 of the other end of the strip. It will be understood that the then meeting end edges of wall 11 will need to be secured together in any suitable manner, such as by welding or the use of an L-strap riveted to the wall end portions.

What is claimed is:

1. A sheet metal corner for a mirror frame, comprising an L-section strip of sheet metal having a continuous side strip bent at substantially a right angle to form a corner and an integral front strip slotted adjacent said corner to form a pair of adjacent mitered edge portions when the said side strip is bent, one of said mitered edge portions having a boss formation positioned to conceal the first mitered edge, said formation being configured to present a pleasing external appearance other than that of a joint between the mitered edge portions.

2. A sheet metal corner for a mirror frame, comprising an L-section strip of sheet metal having a continuous side strip bent at substantially a right angle to form a corner, and a front strip slotted adjacent said corner to form a pair of adjacent mitered edge portions, one of said mitered edge portions having a boss formation overlying the mitered edge of the other portion to conceal it, said boss formation having edges spaced from the adjacent mitered edge portions and being configured to present a pleasing appearance other than that of a joint.

3. A sheet metal corner for a mirror frame, comprising an L-section strip of sheet metal having a continuous side strip bent at substantially a right angle to form a corner and an integral front strip slotted adjacent said corner to form a pair of adjacent mitered edge portions, one of said mitered edge portions being in the form of an embossed rib overlying the other mitered edge portion and having a configuration presenting a pleasing appearance other than that of a joint.

4. A sheet metal corner for a mirror frame, comprising an L-section strip of sheet metal having a continuous side strip bent at a right angle to form a corner and an integral front strip slotted adjacent said corner to form a pair of adjacent mitered edge portions when the strip is bent, one of said mitered edge portions having an outwardly embossed end part overlying the other mitered edge portion, the embossed end part being configurated to present a pleasing external appearance other than that of a joint between the mitered edge portions.
